Product details

0.4 W Zener — small-signal regulation diode

The HZK9ALTR-S-E is a 0.4 W Zener diode from the * series, designed for low-current voltage regulation and clamping in small-signal circuits. Its 0.4 W power dissipation ceiling defines the thermal budget — at 25 °C ambient, the part can handle 400 mW of continuous power; above that, derating applies per the standard Zener curve.

Frequently asked questions

What is the power dissipation of HZK9ALTR-S-E?

The HZK9ALTR-S-E is rated for 0.4 W power dissipation. This is the maximum continuous power the Zener can dissipate at 25 °C ambient; operation above this temperature requires derating.

Is HZK9ALTR-S-E RoHS compliant?

Yes, the HZK9ALTR-S-E is ROHS3 Compliant, meaning it meets the latest RoHS directive without exemptions.

What package does HZK9ALTR-S-E come in?

The HZK9ALTR-S-E is supplied in Bulk packaging — loose parts, not tape-and-reel. Suitable for low-volume or hand-placement assembly.
